发布时间：2020-12-25 01:24

　　本文以阿尔法磁谱仪（AMS）电子设备热控制系统为研究对象,基于实际飞行数据,论证了热控系统设计思路的正确性和有效性,分析了阿尔法磁谱仪探测器热控制系统在轨运行的基本规律,研究了国际空间站（ISS）的操作对阿尔法磁谱仪热控制系统的影响,分析了在运行过程中出现的温度预警现象规律和原因,并提出了基于调节热环境的热控制建议。本文首先介绍了AMS实验的目的、意义以及已经获得的物理学结果。本文分析了国际空间站上的外部热环境、AMS自身内部热负荷情况以及热要求,介绍了AMS热控制系统的方案。由于例子探测需要以及与国际空间站相配合,AMS热控制系统设计思路与以往航天器的“完全包覆式”热控制不同,AMS热控制设计使用了大热容材料应对近地轨道热环境的周期性剧烈变化。电子设备热控制系统实际运行数据表明,电子设备成功启动,启动过程温度曲线与模拟结果吻合；断电时各电子箱均能保持在最低存活温度以上；热工况中各电子箱温度低于最高存活温度；轨道周期内温度波动处于允许的范围内。长时间飞行数据证明了热控制系统设计思路的正确性以及热控制系统的有效性。AMS在国际空间站上运行后,在监控过程中发现,AMS热控制系统运行状态受到...
